WebSep 29, 2024 · CRGP and Default Interface Methods. Similar to regular interface methods, the Curiously Recurring Generic Pattern can enhance the type safety of default interface methods if necessary. This is similar to using CRGP with base types, except interfaces cannot have state. Put another way, this enables strongly-typed traits, but falls short of … WebMay 17, 2011 · The key to the technique is the strange template trickery that's being used: note that Derived inherits from Base.What gives? The idea is to "inject" the real type of the derived class into the base, at compile time, allowing the static_cast of this in the interface to produce the desired result.

More generally it is known as F-bound polymorphism, and it is a form of F-bounded quantification. See more The technique was formalized in 1989 as "F-bounded quantification." The name "CRTP" was independently coined by Jim Coplien in 1995, who had observed it in some of the earliest C++ template code as well as in code … See more The main purpose of an object counter is retrieving statistics of object creation and destruction for a given class. This can be easily solved using CRTP: Each time an object of class X is created, the constructor of counter is called, incrementing both … See more When using polymorphism, one sometimes needs to create copies of objects by the base class pointer. A commonly used idiom for this is adding a virtual clone function that is defined in every derived class.
